Electrical device powered through neutral or ground

摘要

An electrical device is provided that can selectively be powered through a neutral wire or an earth ground. The electrical device includes a line terminal, a neutral terminal, a ground terminal, and a selection mechanism. The line terminal is electrically connected to at least one load. The line terminal can be electrically connected to a line (or “hot”) wire. The neutral terminal is electrically connected to the at least one load. The neutral terminal can be electrically connected to the neutral wire. A first electrical path is provided from the line terminal through the at least one load to the neutral terminal. The ground terminal can conduct current to the earth ground. The selection can selectively provide a second electrical path from the neutral terminal to the earth ground via the ground terminal.

1. An electrical device configured for selectively being powered through a neutral wire or an earth ground, the electrical device comprising:
a line terminal electrically connected to at least one load and configured to be electrically connected to a line wire for receiving current from a power supply; a neutral terminal electrically connected to the at least one load and configured to be electrically connected to the neutral wire, wherein a first electrical path is provided from the line terminal through the at least one load to the neutral terminal; a ground terminal configured to selectively conduct current to the earth ground; and a selection mechanism configured to selectively provide a second electrical path from the neutral terminal to the earth ground via the ground terminal.
